TressFX Hair: Cross-platform and v2.0

Its beside the point anyhow - but its a bit of an ingenuous claim for AMD to make without further clarification.

Yes its besides the point but still a misconception of Physx use that get perpetuated non the less.
And as i have already said AMD needs to clarify, maybe the first GPU compute realtime ingame usable multi plaftform ect...

I know Alice Madness returns uses some form of Hair physics and that was 2011. Looks very good as well and no clipping like TressFX.
 
Good to hear how TressFX2.0 just like the first one works fine on all multiple platforms fine without a performance loss. The first one worked as fine on my GTX660 as well as my mates HD7850 in TR. I don't see why certain people are bitching and moaning about it - if you hate it just don't play the games with it in or switch it off.

Yet in the Hairworks thread,very little of the nonsense negative crap in this thread which is already been derailed about more crap abut Mantle and silly OCD! Like we don't aleady have a billion bloody threads about it! :rolleyes:

We should all be excited that BOTH Nvidia and AMD are promoting physics applications which at least are now starting to become cross platform,as opposed to working on one vendors hardware only,like this post I made in the Hairworks thread:

Personally after playing many 3rd person games,it is nice there will be better hair and fur physics in games. Valve pushed massively forward with facial animation in HL2 as it needed to be done. We already have ragdoll physics for bodies and things like motion scanning for realistic body motion modelling,and tessellation to make surfaces look more realistic. This is the next step in making more realistic models of people and animals in games.

At least that is some indication they are starting to play nice(r) with each other,which is what some of you lot fail to see,since you so focused on your little microcosms.

It also means consoles will have more games with it bringing things like hair and fur physics to a much bigger audience which is a plus for gamers. Nvidia would want to see good adoption of the tech on consoles since it also means good adoption in multi-platform games,meaning they would have to improve performance anyway on non-NV hardware at some point and AMD would like to see TressFX in more games and since NV is a significant player in the PC market,it makes sense they play nice too. At least that is my hope.

I love the quote

TressFX Hair was the world’s first real-time hair physics simulation in a playable game

Never mind its not accurate.

Whats not accurate and why?

TressFX wasn't the first hair physics at all and I don't know about other games but Alice Madness returns was released on June 17th 2011, whilst Tomb Raider was released on 5th March 2013 (almost 2 years after Alice: Madness Returns.

So AMDs claims are complete tosh then...

Yer, seems so and I was searching to see if it was locked down to nVidia only and appears it isn't....

PhysX Low - basic CPU physics, similar for PC and consoles. Interesting note: physically simulated clothing and hair for Alice are not part of hardware PhysX content, and are not affected by PhysX settings (moreover, it is not even using PhysX engine for simulation).

AMD choice, it's not law.
It'd be like Google Maps working better on Google Android than Apple iOS. Why shouldn't it?
It's like MSI GPUs boosting automatically if paired with an MSI motherboard but not with any other vendors motherboard. It's a perk you get for putting the effort in, if someone chooses not to it's up to them.

It's not a legal requirement to make something work as well for a competitor as for yourself. However, to deliberately cripple performance on a competitor is illegal - as would your MSI example be if they did it. There are ways around these laws, loads of them, but to say there are no such laws is not correct.

We've no evidence that hairworks is deliberately crippled on AMD hardware though, just that it's not written in a way that runs very well on their kit. However, that is a win for TressFX as if it runs well on both then it is better than it's rival that only works well on one. Of course, you can always write something as only working at all on your own kit, at which point it can be marketed as a feature of your stuff and provided it's not viewed as essential to the market then you're fine, but adoption rates suffer. It working for everyone but better for you is preferable as then it makes your kit look faster by having a specific scenario where it works better.

Such a shame that Rise of the Tomb Raider is a timed exclusive for the XBone, as I loved the hair in the 2013 game and these subtle touches are great additions in my opinion. More of it though please :)

Carry on and ending up looking daft in this scenario comparing apples n oranges using Mantle as base of acceptability, it's your choice.:)

And why is that?
One's an API and ones is a library, but why shouldn't the same apply?

I'm pretty sure that's what happens with MSI motherboards and graphics cards (my friend bought them forthis very reason).

It's interesting that AMD say they have been able to accurately time exactly how long the code is taking to calculate the hair in HW down to specific routines. Given that not too long ago we were subjected to a big song and dance about how it was all an evil black box that nobody could do anything with and that poor old AMD could never analyse what was going on without access to source code.


Fancy that. If you can accurately analyse code to this level, you can certainly see what is going on in order to optimise things, why then do AMD keep holding back performance for their users, it's their customers losing out for nothing more than to prove a point. :(

I hope they have something better than second rate forum bait like this in order to counter the 9x0 launch. If not things are not going to be pretty over the next few months.

Because it's all obnoxious politics. They're not exactly going to do the other team a favour and use the latest drivers for example. The GW argument is nothing but instigating baseless bigotry. Tomorrow better have more than TressFX announcements. Albeit TressFX did look amazing in Tomb Raider. Going to take a few more games to grab present attention.
